The episode as NWS LWX wrote it up.
A stationary boundary remained over central on the 28th. An easterly flow off the Atlantic Ocean pumped in plenty of moisture. Showers and thunderstorms developed near the boundary. Due to a light steering flow aloft showers and thunderstorms were slow to move. Therefore, heavy amounts of rain fell in short periods of time across portions of central Virginia.

NWS Baltimore/Washington wrote its last area forecast discussion before the first event at May 28, 1:54 PM EST, 3 hours 46 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
254 PM EDT FRI MAY 28 2010
.SYNOPSIS...
A FRONT WILL MOVE WESTWARD TOWARD THE APPALACHIANS THIS
AFTERNOON...WHILE HIGH PRESSURE SETTLES OFF THE MID ATLANTIC
COAST. HIGH PRESSURE REMAINS IN CONTROL ON SATURDAY. A BACKDOOR
FRONT MOVES SOUTH OF THE REGION SATURDAY NIGHT. HIGH PRESSURE
RETURNS SUNDAY AND MONDAY. ANOTHER COLD FRONT CAN BE EXPECTED
TUESDAY.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
NORTH-SOUTH ORIENTED FRONTAL BOUNDARY RESIDES ACROSS THE HIGHLANDS
THIS AFTERNOON. THIS AND HIGHER TERRAIN WILL SERVE AS INITIAL
TRIGGERS FOR CONVECTION EARLY THIS AFTERNOON. CONVECTION WILL BE
SLOW TO MOVE...BUT WILL LIKELY WIND UP EXHIBITING A SOUTH OR
SOUTHEAST DRIFT WITH TIME.
SEVERE WEATHER RISK WILL LIKELY BE RELEGATED NEAR/WEST OF THE BLUE
RIDGE AND INTO THE CENTRAL VA FOOTHILLS THROUGH EARLY
EVENING...WHERE UP TO 2000 J/KG OF SURFACE BASED CAPE WILL RESIDE.
SEVERE WEATHER RISK FOR LARGE HAIL AND DAMAGING WIND GUSTS WILL
CONTINUE UNTIL SUNSET. CAPE IS SIGNIFICANTLY LESS FURTHER EAST
TOWARD THE INTERSTATE 95 CORRIDOR DUE TO A MORE STABLE EASTERLY
FLOW. SO WHILE THE METRO AREAS HAVE A DECENT CHANCE OF SOME
CONVECTION TOWARD EVENING...INTENSITY WOULD BE LESS.
THERE WILL ALSO BE A HEAVY RAINFALL RISK IN ROUGHLY THE SAME AREA AS
THE SEVERE RISK GIVEN HIGH MOISTURE CONTENT AND RELATIVELY SLOW
STORM MOVEMENT AND ALSO THE POTENTIAL FOR TRAINING. ALSO HAVE
CONSIDERED YESTERDAYS RAINFALL WHICH HAS RESULTED IN LOWER FLASH
FLOOD GUIDANCE ACROSS THE HIGHLANDS/SHENANDOAH VALLEY AREA. FLASH
FLOOD WATCH IS IN EFFECT THROUGH THIS EVENING.
FRONTAL BOUNDARY LIKELY WASHES OUT OVERNIGHT. CONVECTION WILL WANE
AS THE NIGHT PROGRESSES...ALTHOUGH STILL CANT RULE OUT A FEW ROGUE
SHOWERS OVERNIGHT. POP/WX/QPF TRENDS WHICH CLOSELY RESEMBLE THE
SREFS REFLECT THIS.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY AFTERNOON/...
STILL MAY HAVE SOME CONVECTION ON SATURDAY...DESPITE THE LACK OF A
STRONG TRIGGER/LIFTING MECHANISM. DEWPOINTS REMAIN FAIRLY JUICY
AND DESPITE BROKEN-OVERCAST CLOUD COVER...SOME INSTABILITY SHOULD
BE REALIZED SO SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP IN
THE AFTERNOON. POPS/WX/QPF LEANS MORE TOWARD NAM/SREFS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
SOME OF THE SHORT TERM GUIDANCE KEEPS IN A REGIME OF SCATTERED
SHOWERS OVERNIGHT SAT NIGHT INTO EARLY SUNDAY...AS IN - NOT ENTIRELY
PUSHING THE COLD FRONT THRU THE AREA TILL DAWN SUN MORNING. THERE
MAY BE A FEW ISOLATED SHOWERS THAT POP-UP OVERNIGHT ACROSS THE AREA
BUT W/ MUCH OF THE FORCING AND INSTABILITY DRIFTING SEWD DURING THE
EARLY MORNING HOURS - THIS ACTIVITY WOULD BE WIDELY SCATTERED AND
SHORT-LIVED...SO POPS HAVE BEEN TAPERED-DOWN OVERNIGHT. THE GFS THEN
PAINTS A NEAR-COASTAL AREA OF INSTABILITY ON SUN AFTN THAT EXTENDS
TO LOWER SRN MD AND LOWER DELMARVA...AND ALSO A TERRAIN CIRCULATION
AREA OF SHOWERS/STORMS OVER THE SWRN PORTION OF THE AREA...BUT THIS
MAY ALSO BE A BIT OVERDONE. EITHER WAY...MAINLY JUST A FEW ISOLATED
AND SHORT-LIVED ACTIVITY.
THE BETTER CHANCES FOR PRECIP WILL THEN ARRIVE FOR MON/TUE AS RETURN
FLOW FROM THE GULF COAST SETS-UP OVER SOUTHEAST AND INTO THE OHIO
VLY. A DEEP UPPER LOW /THAT IS CURRENTLY AFFECTING THE PAC NW AND
NRN ROCKIES/ WILL SLIDE OVER SOUTH CENTRAL CANADA OVER THE WEEKEND
AND EVENTUALLY DRIFT TOWARD THE NRN GREAT LAKES BY EARLY NEXT WEEK.
THIS FEATURE WILL BE ENOUGH TO HELP DRAW A LARGE-SCALE AREA OF
MOISTURE...AS MENTIONED UP ACROSS THE DEEP SOUTH FOR THE NORMAL
SUMMERTIME DIURNAL AFTN STORMS ACROSS THESE AREAS. HIGH PRESSURE AND
A WEAK UPPER RIDGE JUST OFF THE SRN ATLC COAST MAY BE ENOUGH TO
CAP-OFF THE ERN SEABOARD ON MONDAY. THE HIGHER TERRAIN OF THE
CNTRL/SRN APLCNS APPEAR TO BE IN THE UNSTABLE REGION ON MONDAY...SO
A BETTER CHANCE FOR RAIN/SOME THUNDER LATER ON MON AFTN/EVE ACROSS
WV/POTOMAC HIGHLANDS AND MORE ISOLATED ACTIVITY BACK TOWARD THE
METRO AREAS.
OVERNIGHT MON...MUCH OF THE ACTIVITY DISSIPATES W/ THE LOSS OF
HEATING AND THEN SETS-UP AGAIN FOR ANOTHER UNSTABLE AFTN ON TUE. BY
THEN...THE UPPER LOW OVER SRN CANADA WILL LIKELY OPEN UP TO THE
UPPER TROUGH AND FORCE THE TROF AXIS TO DIVE DOWN A BIT FURTHER
SOUTH INTO THE GREAT LAKES TUE AFTN. THIS WILL ADD MORE DYNAMICS TO
THE ATMOSPHERE THAT WILL BE IN PLACE FROM THE GULF COAST TO NEW
ENGLAND ON TUE AFTN/EVE. WIDESPREAD SHOWERS/STORMS SHOULD DEVELOP
ACROSS THE REGION...AS A COLD FRONT THEN PUSHES ACROSS THE I-95
CORRIDOR LATER IN THE EVENING. THE FRONT WILL DRIFT DOWN ACROSS THE
CAROLINAS...STALLING OUT FOR A COUPLE OF DAYS BEFORE THE NEXT
SHORTWAVE DIVES DOWN INTO THE OHIO VLY FROM THE NRN PLAINS FOR THE
END OF THE WORK WEEK.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
THUNDERSTORMS ARE LIKELY AT KCHO/KMRB THIS AFTERNOON...AND MAY
AFFECT THE HUBS TOWARD EVENING. IN LINE WITH SREFS/CCFP...HAVE
INCLUDED TEMPO GROUPS FOR MVFR CONDITIONS IN THUNDERSTORMS DURING
MOST LIKELY TIME FOR CONVECTION. LATER ON TONIGHT...EXPECT LOW
CLOUDS WITH IFR CIGS TO DEVELOP...AND PERHAPS MVFR FOG AS WELL. THIS
WILL IMPROVE SATURDAY MORNING. SCATTERED THUNDERSTORMS POSSIBLE
AGAIN SATURDAY AFTERNOON.
A COLD FRONT WILL SLOWLY CROSS THE REGION LATE SAT INTO EARLY
SUNDAY...PUSHING MUCH OF THE PRECIP TO THE SOUTHEAST. SUNDAY INTO
MON WILL BE A DECENT TRANSITION PERIOD WILL VFR CONDITIONS...JUST
AHEAD OF THE NEXT FRONTAL PASSAGE. MON AFTN/EVE...SCATTERED AREAS OF
RAIN/TSRA WILL BEGIN TO MOVE INTO THE APLCNS BUT ONLY A FEW ISOLATED
STORMS INTO THE I-95 CORRIDOR. MORE ACTIVITY IS EXPECTED TO MOVE
INTO THE REGION ON TUE...JUST AHEAD OF A COLD FRONT. THE FRONT WILL
MOVE JUST TO THE SOUTH OF THE AREA THRU MID WEEK...ALLOWING HIGH
PRESSURE TO BUILD BACK INTO THE MID ATLC.
&&
.MARINE...
MARGINAL SMALL CRAFT ADVISORY CONTINUES THROUGH THIS EVENING UNDER
EASTERLY FLOW REGIME. FAVORED THE NAM WHICH FAVORED MORE OF A
SOUTHEAST OR SOUTH TYPE WIND FLOW ON SATURDAY...BUT AT LEVELS BELOW
SCA THRESHOLDS.
LIGHT WINDS EXPECTED THROUGH THE WEEKEND AND INTO THE MIDDLE OF NEXT
WEEK. A COUPLE OF FRONTAL PASSAGES DURING THIS TIME...BUT MAINLY
BRINGING SOME SCATTERED SHOWERS/STORMS W/ EACH PASSAGE. THE FIRST
FRONT WILL PASS OVER THE WATERS LATE SAT NIGHT...A COUPLE OF DAYS OF
HIGH PRESSURE - THEN ANOTHER COLD FRONT LATE TUE.
&&
.TIDES/COASTAL FLOODING...
DURING HIGH TIDE EARLY THIS MORNING...MINOR TIDAL FLOODING
THRESHOLDS WERE REACHED AT THE USUAL SENSITIVE LOCATIONS SUCH AS
ANNAPOLIS AND ALEXANDRIA WITH 1 TO 1.5 FEET ANOMALIES UNDER A FULL
MOON. THESE ANOMALIES WILL CONTINUE THROUGH AT LEAST THE NEXT COUPLE
OF HIGH TIDE CYCLES AND MAY INCREASE A LITTLE. THE NEXT HIGH TIDE
CYCLE IS THE LOWER OF THE NEXT 2. HAVE MODERATE TO HIGH CONFIDENCE
IN THE SECOND REACHING MINOR TIDAL FLOODING THRESHOLDS BUT THE FIRST
MAY BE MORE MARGINAL...BUT THE FIRST WILL BE CLOSE ENOUGH WHERE WE
WILL ISSUE A COASTAL FLOODING ADVISORY FOR THE FOLLOWING 2 CYCLES
GIVEN THE FORECAST ANOMALIES WITH A FULL MOON.
